Embodiment 1

[0033] (1) Assembly of PTCD-cys / Au-ZIF-67 / GCE sensor

[0034] (1) Preparation of PTCD-cys and Au-ZIF-67 materials:

[0035] Accurately weigh 0.0716g of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA), 0.1602g of L-cysteine ​​(L-cys) and 6.0034g of imidazole in a three-necked flask, under argon Heated at 100°C for 6h under gas protection. The reaction mixture was cooled to room temperature and dispersed in 25 mL of ethanol, then 125 mL of hydrochloric acid solution (1M) was added. The mixture was stirred overnight. The resulting red solid was filtered and washed with water until the filtrate became neutral. The filter cake was vacuum-dried, and the resulting red solid was PTCD-cys, which was stored at 4°C.

[0036] Accurately weigh 0.2912g Co(NO 3 ) 2 ·6H 2 O and 0.6608 g of 2-methylimidazole were dissolved in 30 mL of methanol. After stirring at room temperature for 24 h, it was centrifuged and washed with methanol three times, and dried in vacuum at 80° C. for 4...

Abstract

The invention provides an electrochemical luminescence sensor for detecting synthetic cannabinoid RCS-4 and a preparation method of the electrochemical luminescence sensor, and belongs to the field of electrochemical luminescence detection. PTCD-cys and Au-ZIF-67 are combined through the electrostatic binding effect, an electrochemical luminescence sensor is constructed, and the synthesized cannabinoid RCS-4 is detected based on the electrochemical luminescence sensor. When in use, the sensor is used as a working electrode, an Ag / AgCl electrode is used as a reference electrode, and a platinum electrode is used as an auxiliary electrode to form a traditional three-electrode system, and the synthetic cannabinoid RCS-4 is detected by an electrochemical luminescence method. The lowest detection limit is 9.32 * 10 <-13 > g / L, and the sensor has the characteristics of simple preparation method, high RCS-4 detection sensitivity, good selectivity and wide linear range.

Description

technical field [0001] The invention belongs to the field of electrochemiluminescence detection, and relates to an electrochemiluminescence sensor for detecting synthetic cannabinoid RCS-4, a preparation method and application thereof. The method involves co-modifying PTCD-cys and Au-ZIF-67 on the surface of a glassy carbon electrode, and using the Au-ZIF-67 / PTCD-cys / GCE electrode as a sensing element to quantitatively detect the synthetic cannabinoid RCS- 4. It belongs to the field of electrochemiluminescence. Background technique [0002] E-cigarettes are electronic products that mimic cigarettes and have a similar look, smoke, taste and feel to cigarettes. It is a product that allows users to inhale after turning the e-liquid into steam by means of atomization and other means. The current common electronic cigarettes are used to replace cigarettes and quit smoking. It has no other harmful components such as tar and suspended particles in cigarettes, and can suck out smo...
